IDPRO'V'EMENT IN PUMPS.

-The Schedule referred to in these Letters Patent and making part of the same.

To all whom lt may concern:

Be it known that I, WILLIAM N. OHAMBERLAIN, of Van Buren, Michigan,- have invented an Improved Pump; and I do hereby declare the following is a full,

- and exact description thereof, reference being had to the accompanying drawings, and to the letters thereon.

Figure 1 is a side elevation ofmypump. Figure 2 is a section, showing the construction and arrangement ofthe several parts thereof.

My object is to make a cheap and an eiicient pump;

.and my invention consists chiefly in the arrangement made round, and to fit at A" the inside of the cylinder.

' The cylinder I make preferably of galvanizediron, and a packing of leather or other suitable material is placed between the wood pipe yand cylinder.

On the sides'of the cylinder are two wings, C and I C", to which two wood rods, D and D", 'are attached. lhe two rods are connected at the top of the well with a pump-handle; and thus the action is to, raise the cylinder over and up on the wood pipe, thus making a lifting force-pump.

There are valves, one, the upper, at the junction of the .wood pipes A and A', and the other at the bottom of the cylinder.

In fig. 2, the same letters/show the same parts, E being the upper, and 'Gry the lower valve, and Hv the packing betweenl the piston end of the wood pipe andthe metallic cylinder.

The advantages and uses of my invention are appa rent to those skilled in the art to which it appertains.

y Claims. p

1. The pipe A, vwith the piece or part A' at itslower end, and holding the valve E on its top, 'in combination with'the cylinder B, and its valve Gr, substantially as and for the purposes set forth. i

2. The combined whole, made by the pipes A A', cylinder B, valves E and G, frame F F', and litting-rods D. D', arranged substantially as set forth.
